keyboard_update(3) Svgalib User Manual keyboard_update(3)
NAME
keyboard_update, keyboard_waitforupdate - process raw key-
board events
SYNOPSIS#include<vgakeyboard.h>intkeyboard_update(void);voidkeyboard_waitforupdate(void);DESCRIPTION
These routines check the keyboard buffer for any raw key-
board events and do the necessary updates to the internal
buffers of keyboard_clearstate(3) and keyboard_key-pressed(3).
When there are no such events, keyboard_update() returns 0
immediately (non-zero else) whereas keyboard_waitforup-date() blocks and waits until an event occurs.
vga_waitevent(3) allows to wait for keyboard and other
events at the same time.
